PRINTING ATTACHMENT FOR ROLL-HOLDERS.

SPECIFICATION forming part of Letters Patent No.- 643,893, dated February 20, 1900.

Application filed April 15, 1899. Renewed November 2'7, 1899- Serial No. 738,450. (No model.)

To otZZ whom it may concern:

Be it known that I, WILLIAM 0. DAY, a citizen of the United States, and a resident of the city and county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Printing Attachments for Rolls of Paper or other Materials, of which the following is a specification.

My invention relates to improvements in printing attachments for rolls of paper and other materials; and the object of my invention is to furnish a printing device which may be attached to any of the frames carrying paper or other materials in rolls to print a name or advertisement on the paper or other material as it is withdrawn from the roll.

In the accompanying drawings, forming part of this specification, and in which similar letters of reference indicate similar parts throughout the several views, Figure 1 is a side elevation of a reel of material furnished with my printing device; Fig. 2, a section of Fig. 3 on line A B; Fig. 3, a front elevation of Fig. 1; Fig. 4, a perspective view of one link of the chain belt and part of the typecarrying trays and one of the type; Fig. 5, a transverse section through the severing-knife, showing attachment for keeping knife clear of the material to prevent blurring of the printing; Fig. 6, a perspective view of the knife-lifting piece before its attachment to the knife.

or is a frame furnished with suitable bearings, which carry a shaft 19, which carries a roll of paper or other material a. dis a knife resting on the roll 0 and extending from one side to the other of this roll. The knife is carried upon arms 6, which are carried by the upper part of frame a and may be heavy enough to remain unmoved when the material is brought against it in cutting, or the arms may be springs forcing the blade against the roll. The construction of all these parts is Well known and will need no further description.

Hinged to the upper part of frame a by hinges f is a frame g, which carries in suitable bearings shafts h 'i 70, the two former of which carry sprocket-wheels Z m, and the latter of which carries friction-wheels n, preferably covered with rubber, and sprocketwheels 0. p are endless chain belts passing around sprockets Z m and engaging the teeth on sprockets 0. Secured to certain opposite links of chain belts n are type-carrying boxes 0, which carry type 5. There may be as many boxes r as may be desired, each box carrying one or more lines of type. it are inking-rollers for inking the type. These rollers are carried by frame g and may be arranged in any suitable manner.

The friction-wheels n bear against the roll of material, and when the material is drawn from the roll these wheels are revolved, turning sprockets 0 and driving chain belts p. The type carried by the chain belts is thus caused to pass in contact with and be inked by the inking-rolls and then to be brought into contact with the material which receives an impression from them.

The roll of material forms a platen for the sheet being printed, and the frame g and its parts are sufficiently heavy to insure. a perfeet contact between the face of the type and the material.

In order that the printing mechanism may operate until all the material is withdrawn from the roll, the centers of shafts b and It should be at the same distance from centers of hinges f.

In order to prevent knife d from coming in contact with and blurring the wet ink as the material is drawn from under it, I have provided a piece of thin metal 1), as tin, one end of which carries a metal or wooden block w, Figs. 1, 2, 5, and 6. The blocks are adapted to be placed one under each side of the ends of the knife, and the thin pieces of metal which carry them are then bent around the knife and block, as best shown in Fig. 5, and engage the material, lifting the knife clear of it.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a printing attachment for paper-rolls, in combination, the paper-roll and its supporting shaft and frame, a frame hinged to the upper part of said supporting-frame, a friction-roll carried by said hinged frame engaging the paper-roll, endless belts driven by the movements of said friction-roll, idlers carried by said frame-supporting belts, type-carrying boxes and type carried by said belts, and means for inking said type.

belts, type carried by said boxes and hiking"- rolis for inking said type.

3. The herein-described device for lifting and holding the cutting-knife clear of the material consisting of a tongue of thin metal carrying a block, said block being adapted to be placed against the under side of said knife and said tongue being adapted to be wrapped around said block and knife.
